Rhinorrhea: All symptoms compatible with chronic non-allergic rhinorrhea. A parasympatholytic nasal spray (atrovent) can be helpful if used pre-exposure.

Sensitivity to cold : You have sensitivity to cold air cold and soicy food smetimes use og steroid nasal drops help prior to exposure but if it is not too bad i will advice no med or consult an allergist.
